What does concrete floor polishing typically cost in the Calgary area?

Concrete floor polishing in Calgary typically costs $3-8 per square foot for basic polishing, with decorative options ranging $8-15 per square foot. The wide price range depends on the existing concrete condition, desired finish level, and decorative elements like staining or scoring.

Basic polished concrete (grinding and polishing existing slabs to a smooth, glossy finish) runs $3-5 per square foot in the Calgary market. This includes grinding down the surface, filling minor cracks, and polishing through progressively finer grits to achieve the desired sheen level. Mid-range projects with light staining or basic decorative scoring typically cost $5-8 per square foot.

High-end decorative polished concrete with multiple stain colors, intricate saw-cut patterns, or aggregate exposure can reach $10-15 per square foot. These projects often include custom design work, multiple stain applications, and specialized finishing techniques that require experienced craftspeople.

Several factors significantly impact pricing in the Calgary area. Existing concrete condition is crucial — newer, well-poured slabs are much easier to polish than old, damaged, or uneven concrete. If your concrete has significant cracks, spalling, or surface irregularities, expect additional costs for repairs and leveling compounds. Accessibility also matters — basement floors or areas requiring equipment to navigate tight spaces will cost more than open warehouse or main floor areas.

Calgary's extreme climate affects concrete polishing projects. The freeze-thaw cycles from chinook temperature swings can cause micro-cracking in concrete over time. Older concrete may need more extensive preparation work, including crack injection and surface repairs, before polishing can begin. Many Calgary contractors recommend sealing polished concrete in residential applications to protect against salt and moisture tracked in during winter months.

What's typically included in polishing quotes: surface preparation, grinding through multiple grits (usually 4-6 steps from coarse to fine), crack filling, and final polishing to the specified gloss level. What's often extra: decorative staining, saw-cut patterns, extensive crack repairs, moisture mitigation systems, and protective sealers. Some contractors include a basic sealer in their base price, while others charge $0.50-1.50 per square foot for premium sealers.

Professional installation is essential for quality results. Concrete polishing requires specialized equipment (planetary grinders, diamond tooling) and expertise to achieve consistent results without creating swirl marks or uneven sheen levels. Poor technique can permanently damage the concrete surface, requiring costly repairs or complete replacement.

Timeline considerations: Most polished concrete projects take 2-4 days for residential spaces, depending on size and complexity. The concrete must be fully cured (typically 28 days minimum for new pours) before polishing can begin. Plan for dust and noise during the grinding process, though modern equipment includes dust collection systems.
